Rhythmic Initiation is best used for:

• teaching of a movement or improved mobility

• reduce tone

• cause co-contraction/stability

• muscle stretching

Answer explanation

Rhythmic Initiation is primarily used for teaching a movement or improving mobility by providing a structured approach to movement patterns, making it effective for learning new skills.

Rhythmic rotation is best used for:

• teaching of a movement or improved mobility

• reduce tone

• cause co-contraction/stability

• muscle stretching

Answer explanation

Rhythmic rotation is effective in reducing muscle tone, making it beneficial for individuals with spasticity. It helps to relax muscles and improve overall mobility, distinguishing it from other options.

Contract-relax is best used for:

• teaching of a movement or improved mobility

• reduce tone

• cause co-contraction/stability

• muscle stretching

Answer explanation

Contract-relax is a technique primarily used for muscle stretching. It involves contracting a muscle before relaxing it, which enhances flexibility and range of motion, making it effective for stretching.

Rhythmic stabilization is best used for:

• teaching of a movement or improved mobility

• reduce tone

• cause co-contraction/stability

• muscle stretching

Answer explanation

Rhythmic stabilization is primarily used to promote co-contraction and stability in muscles, making 'cause co-contraction/stability' the correct choice. It enhances joint stability through controlled muscle activation.

Combination of Isotonics is best used for:

• improving postural muscles

• poor antigravity control

• improve motor control/learning how to move

• improving ROM

Answer explanation

Combination of Isotonics is effective for improving postural muscles as it enhances strength and stability, which are crucial for maintaining proper posture. This choice directly addresses the need for postural support.

• D2 Flexion

• D1 Flexion

• 
  D2 Extension

• 
  D1 Extension

Answer explanation

D1 Flexion is the correct choice as it involves the movement pattern demonstrated in the video, which focuses on flexing the arm across the body, characteristic of D1 Flexion.

• D2 Flexion

• 
  D1 Flexion

• D2 Extension

• D1 Extension

Answer explanation

D1 Extension is the correct choice as it involves moving the arm away from the body in a diagonal pattern, which is characteristic of D1 extension. The other options do not accurately describe this movement.

• D2 Flexion

• D1 Flexion

• 
  D2 Extension

• D1 Extension

Answer explanation

D2 Flexion is the correct choice as it refers to a specific movement pattern in the D2 diagonal pattern of proprioceptive neuromuscular facilitation (PNF), which involves flexing the arm across the body.
